The RDSO — the Indian Railways’ Research Development and Standards Organization — offers tips for persons who will be taking their job application tests. These tips, offered by RDSO’s Psycho Technical Directorate, include two that may be obvious to some applicants: If you wear glasses or a hearing aid, be sure to take them with […]

Ambitious railway plans
Who does not love an ambitious railway plan? The Guardian reports about a report about Chinese “plans to build a high-speed railway line to the US: The proposed line would begin in north-east China and run up through Siberia, pass through a tunnel underneath the Pacific Ocean then cut through Alaska and Canada to reach […]
Why it will take 6,000 dead goats to build Britain’s high speed railway
A new UK railway project will indirectly require thousands of dead goats, explains the IanVisits Blog. It’s a matter of vellum: If, or when the High Speed 2 railway is constructed, it will require roughly 6,000 dead goats. This curious statement comes from an old technicality as Acts of Parliament, when passed into law are still […]
Railway vibrations – part 2 ‘Jiggling’
We’ve previously looked at the role of the rail track and wheels in inducing vibrations in trains – (see: Railway vibrations – part 1 – Graunching ) now it’s time to turn to the effect of vibrations on the rail passengers themselves. Dr. David Bissell – a lecturer at the Australian National University’s College of […]
Railway vibrations – part 1 – ‘Graunching’.
One of the first technical papers to reference ‘Graunching’ was ‘Railway Noise: Curve Squeal, Roughness Growth, Friction and Wear’ (Report: RRUK/ A, 2003, D.J. Thompson, A.D. Monk-Steel, C.J.C. Jones. P.D Allen, S.S. Hsu, and S.D. Iwnicki) “Other related forms of curving noise include ‘graunching’ at switches and crossings (possibly due to flange rubbing), [and] ‘juddering’ […]
Railway-collision ejection-capsule
In case two trains were about to collide head-on, this emergency ejection capsule would allow at least one person, likely the train engineer, to escape. The scheme was described in a magazine article in 1915. The blog Technologia Obsoleta spotlighted it recently. BONUS: An alternate solution, devised by Flann O’Brien
